You Tell Me I'm to Become the Next Demon Lord After I Marry the Hero?

“Have some tea, Hero.”

“Hero, I've made you a meal.”

“Hero, let me wash your back.”

“Hero, the bed is nice and warm.”

“Hero...”

Who doesn't know that the current Hero's wife, Ainovi, is an adorable little sweetheart who is thrifty and good at keeping house? She's a demon, yet she's got the strongest Hero in history wrapped around her finger.

But only Ainovi knows that this is all just a temporary measure. One day, she'll trample the Hero beneath her feet and take her rightful place as the next Demon King!
